Being Forgetful

Just 30 minutes to go before we leave for Heathrow... what I mean is before I take N to Heathrow (as I'm leaving on Tuesday with my Mum and T). At least N and I will only be separated for 3 days this time! This morning I thought of something which I wanted to remind N of but I promptly forgot what it was - so I have this nagging feeling we may have forgotten something important to take...
